On my current build, supercharged BBC 454 I chose to go with a copper head gasket for better sealing under boost. I am confused on the type of prep I should apply to the gasket before installation. A quick google search said "Hylomar" was a good sealer for head gaskets. Is this required for the copper gasket?

Street driven, weekend cruiser. 7lbs boost (max)
Thank you.

Actually, on a street motor, with only 7 lbs. boost.. I wouldn't use copper gaskets. But, when I was racing BBC's. I just sealed copper gaskets with silver/chrome based cheap spray paint. Sometimes a little silicone gasket sealer around upper water crossover holes (if gasket was a good used one). Just spray a heavy coat of silver paint both sides. Let dry, then a second heavy coat of paint. Install wet. Torque heads and run..

On the street I like Victor/Reinz head gaskets..

Thanks Bob for the reply.

I just figured out that I have the wrong set of gaskets anyway. I am going to s end them back to Summit and hopefully get a exchange. I ordered the set that requires the heads to be fitted for O rings. I waited almost three months for the wrong set of gaskets.

This whole build is starting to be a PITA. Wish I had never started, but I am so far in to it ($$$$$) I can't turn back. I only hope that when I get her completed that the blower will be worth the effort.

The blower snout is too short, had the switch to a short water pump, the lower blower pulley was wrong, alternator bracket doesn't fit, blower belt ideler pulley doesn't fit, ect. JUST A PITA

Thanks Bob.

I think most people are using the cometic layered gasket nowdays. I -personally don't like o-ring w/copper gaskets, they are hard as hell to seal up. JMPO
